Source Select
0:
• Receive mode
When the number of received messages has met the
condition set by the CFIGCV[2:0] bits, a FIFO receive
interrupt request is generated.
• Transmit mode
When the buffer becomes empty upon completion of
message transmission, a FIFO transmit interrupt
request is generated.
1:
• Receive mode
A FIFO receive interrupt request is generated each
time a message has been received.
• Transmit mode
A FIFO transmit interrupt request is generated each
time a message has been transmitted.
